I had mine also very tail touchy and flying it on a transmitter without expo capability

CG was about 5 3/4 after adding some weight. Oh boy..... I really had to fight it to land without crashing. Hovering however was just awsome

. After about 3 flights I decided to move the CG forward to 4 1/2, and I have been flying her like this since. It still is a very touchy plane if flying on high rates. I almost always have to trim her out due to wind directions and speed. Otherwise I love her. my everyday flyer.
Billy, do you like the Knife better for hovering, and all over performance ? I am thinking of either getting a Knife or CG Extreme 330. Really wondering which one hovers and performs better ?
